Today, I will talk to you about how to implement the git automation deployment php script, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following content for you. I hope you can get something from this article.

Git automatic deployment of php script implementation method: 1, install git;2, clone warehouse code; 3, change linux permissions, modify configuration; 4, add www users to sudoers;5, generate key; 6, fill in webhook domain name, upload php script.

This article operating environment: linux5.9.8 system, Git version 2.30.0, DELL G3 computer

How to automate the deployment of php scripts in git?

Git+php deploys webhook automation scripts to implement code synchronization this article will introduce git+php deployment of webhook automation scripts to achieve code synchronization

Git with webhook automatic deployment is not an advanced technology, but I have taken a lot of detours in my first deployment. I am mainly a chicken in linux. This article records the problem points that are easy to make mistakes and the holes encountered.

Prepare for

Deploy accessible web domain name, server php script, warehouse code cloud gitee in lnmp environment

Automate the process, local push- > gitee warehouse webhook- > linux server php script pull

First, create a warehouse on the gitee cloud

The local ssh protocol is used to communicate with the warehouse. My local is windows. How to generate the ssh public key is not described here, but will be described below under linux.

1. Install git

Yum install git

two。 Clone warehouse code "be sure to use the ssh protocol, which is all based on ssh"

Git initgit clone git@gitee.com:zhuyanbin/HiAdmin.git

3. Change linux permissions, modify configuration

Because we webhook to notify the server that it belongs to external access, the administrator user here is the www user by default, so we need to give www sufficient permissions.

Vim / etc/passwd add the following line www:x:1001:1001::/home/www:/bin/bash

1001 is the id of the user group. Use the following command to view the id of the user www

Cat / etc/group

Add www users to sudoers and execute shell without a password

# (1) add permission to write to sudoers for the current user

Chmod Ubunw / etc/sudoers

# (2) Edit sudoers

Vim / etc/sudoers

# (3) search for Allow root to run any commands anywhere and write the following under the line corresponding to the root user:

Www ALL= (ALL) NOPASSWD:/usr/bin/git

# (4) revoke the write permission to sudoers

Chmod Umurw / etc/sudoers

Modify php-fpm.conf configuration settings visitors. Here is www, that is, the default configuration of php.

4. Finally generate the key (this step must be the www user-generated key, ps: stuck in this place for two days, has been using the root administrator account generation, Baidu for several days, tried various methods, and then switched to all ok after the www user-generated key)

Generate a public key

Mkdir-p / home/www/.sshchown-R www.www / home/www/.sshssh-keygen-t rsa

View public key

Cat / home/www/.ssh/id_rsa.pub

Copy the generated public key to the public key of the gitee Code Cloud Warehouse

Https://gitee.com/profile/sshkeys

Add: there are two places for gitee to fill in the public key, one is the public key of the warehouse, if you enter the public key of the warehouse, the git permission of the server will only have the permission of pull, and the other is the public key of the account. If you enter the public key of the personal account, you will have pull,push and other permissions. I use the public key of the personal account directly here.

5. Finally, fill in the webhook domain name and put on the php script

Enter the domain name of the webhook notification address (the password setting is empty, and there is no password verification in the following php. If security is considered, please set the password later)

Use the php script handler hook.php (execute linux command)

Chdir ("/ home/wwwroot/default/HiAdmin"); exec ("git pull origin master 2 > & 1", $out); foreach ($out as $v) {echo iconv ('GB2312','UTF-8', $v). "

";}

At this point, after configuring the above server code, you can automatically synchronize and complete the automatic deployment.

There is a problem

1.php script does not execute

The reason is that many functions of php in php.ini are not opened by default, including executing linux script functions exec (), shell_exec () and so on.

Find php.ini, find the disable_functions line, delete the corresponding function, or comment out the whole line.

two。 Unable to execute git pull command

Question one

Host key verification failed.

Fatal: Could not read from remote repository.

Please make sure you have the correct access rights

And the repository exists.

In the final analysis, it is because of the problem of linux permissions. What I have encountered is a problem.

The reason for this is that root generates the git public key, and after switching to www, the public key is generated successfully (the fourth step above is to generate the public key, which must be generated using www)

Question two

Error: insufficient permission for adding an object to repository database .git / objects

Fatal: failed to write object

Fatal: unpack-objects failed

This still does not have permission to execute the git command, you only need to execute the following

Step 1: cd .git / objects locate the objects file under git. Next step: ls-al to view the owner of the git library (git user git group) step 3: chown-R yourname:yourgrounp * or sudo chmod 777-R. git / objects submission

Finally, after solving the above problems, the work is done. The last successful screenshot

Its own back-end language is php, which can be implemented in a variety of ways to execute linux scripts, nodejs,python, etc.

After reading the above, do you have any further understanding of how git automates the deployment of php scripts? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
